[OBOE] OBOE - g2c deprecated in gcc-4.4 (used in Ubuntu 9.10 - karmic)

[Berit Løfstedt]

Dear Nidhi,

Thank you for your swift reply - I have succeeded in compiling and executing the code now.

What I had to do to make it run on UBUNTU 9.10 was:

Edit configure.ac: 
In OBOE_LDADD: change -lg2c to -lgfortran and remove $BLAS (as libblas.a is dependency of liblapack (see http://old.nabble.com/problem-with-LACAML-and-static-linking-td21700788.html)

install libtool:
sudo apt-get install libtool

After make install in OBOE/:
Remove the libtool dir
Make a symbolic link to libtool
ln -s /usr/lib/libtool .

I will try to implement the active set of Babonneau to the MCF dir.

Hello Berit,





First, in AccpmLASolve.C, line111 , the 4. argument &A(0,0) raises a casting problem, which can be resolved by changing to A.addr() - According to http://lapackpp.sourceforge.net/html/classLaGenMatDouble.html#c700d02217d67ef7a2a5810c59e04a4e

After this "make" and "make install" runs smoothly, but make check fails.
Thanks for pointing that, I think its because the new compilers are more stringent.

Firstly, libtool is installed locally in the OBOE library and is an older version. Hence some of the commands are unknown.

make  Test
make[3]: Entering directory `/home/berit/svn/MCF/src/OBOE/src/AccpmLA'
/bin/bash ../../libtool --tag=CXX   --mode=link g++  -O3 -Wall -L./    -o Test MatrixTest.o libaccpmla.a /usr/local/lib/liblapackpp.la<http://liblapackpp.la> /usr/lib/liblapack.a /usr/lib/libblas.a -lg2c

../../libtool: line 810: *** Future versions of Libtool will require -mode=MODE be specified.: command not found

The main problem is however that the linker cannot find g2c.
In gcc-4.4 g2c is deprecated (see https://bugs.launchpad.net/ubuntu/+source/gcc-4.4/+bug/477278  )

Now gfortran is used and it does not contain g2c. libg2c0 can be found as a package, but linking it staticly actually requires building libg2c from scratch. As of now I have spent about 3 working days getting OBOE to work properly and I am wondering whether I could simply use gfortran? I suspect that the dependency to g2c migt have swapped to gfortran as it is blas, lapack and lapackcpp which has the dependendy. These source codes have new releases (the current version of lapackcpp is 2.5.2 which compiles neatly with gcc-4.4) and hence are probably not dependent on g2c. Do other parts of the code have g2c dependencies?

Yes, as you think the g2c dependency comes only from blas and lapack, I havent tried gfortran so cant say if it could somehow be swapped.

Which version of Ubuntu was the wiki instruction made for? Downgrading might solve my problems :-)

I am notr sure which version it was, I am hoping Laurent Drouet (copied in the email) might be able to answer that as he was involved in the making it wokr on Ubuntu. Will keep you informed if I find out more.
